Course Expectations This is a hard class ◮ While this class is required for several majors as a capstone, it is also an introductory class for CS majors. ◮ You have signed up to learn programming in C++. At the end of the course, you should be a competent entry-level C++ programmer. ◮ However, this involves a lot of
Course Expectations Effort! ◮ Programming is a skill. Almost anyone can be trained to do it well. ◮ You need to devote time outside class to practice. Practice is the only way to better yourself as a programmer.
Course Expectations Reading ◮ Please read through the entire write-up a couple of times to understand the requirements before asking questions. ◮ Most of the assignments/ problem statements will be long. Jumping the gun without reading the whole thing could be detrimental.
Course Expectations Basic Arithmetic ◮ You will not be allowed calculators for the test. However, you will be expected to do some very basic math operations on your tests. ◮ You are being forewarned. Math is not scary.
Course Expectations Start Early! ◮ You will be given a week to 10 days for homeworks. Please start early. You need that amount of time to complete them.
Course Expectations Attendance ◮ The class is very incremental. So, skipping a few classes will get you into trouble. You are expected to attend class. ◮ While we understand that sometimes, circumstances result in missing a couple of classes, missing quite a few classes is not condoned.
Course Expectations Retention ◮ The class is very incremental. Material introduced in one class will be applied through the rest of the course. Retaining material is important. There is no modularization of material. ◮ Please make sure you understand a concept before we move on to the next. We are ok with repeating material.
Course Expectations Ask for help! ◮ The instructor and the TA’s are available to help. Please do not hesitate to ask for help. ◮ We are willing to work with you to ensure you are learning the material. However, this requires that you start the assignments early.
Academic Honor Code ◮ Of late, we have been having a lot of issues with violations of the Academic Honor Code. ◮ Since this is your first programming class, the rules might be a bit ambiguous. We will try to clear up any confusion here. ◮ What is allowed: ◮ Asking the instructor of TA for help ◮ Discussing concepts in general, discussing the concepts used in an assignment. ◮ Getting a tutor to help you with concepts and ideas. ◮ If you have a question about what counts as a violation to the honor code, please ask the instructor or the TA’s.
Academic Honor Code This is a list (inexhaustive) of things that violate the Academic Honor Code ◮ Copying another person’s solution (changing variable names won’t help). ◮ Giving another person your solution. ◮ Telling another person how to solve the problem. ◮ Hiring a tutor to solve the problem for you. ◮ Asking friends/family to solve the problem for you. ◮ Copying solutions from the internet. ◮ Hiring people on the Internet (including websites like chegg) to solve the problem for you. ◮ Turning in older solutions if you’re repeating the class. ◮ Working with another student (collaboration).
Student Expectations The most common student expectations from the survey
We have technology!
Main Components of a computer ◮ CPU - Central Processing Unit: The “brain” of the computer. ◮ ISA - Instruction Set Architecture: the specific set of low-level instructions available to a CPU. Differs for various CPU types (Intel Pentium, Mac G4, etc). ◮ ALU - Arithmetic & Logic Unit responsible for performing arithmetic calculations, as well as logical operations (comparisons for equality, inequality, for instance). ◮ Main Memory (RAM - Random Access Memory). ◮ storage close to CPU ◮ Faster to access than hard disk ◮ stores executing programs and data being currently worked on ◮ Secondary Memory ◮ SSD, hard disk, DVD, etc.
Main Components of a computer ◮ Input devices ◮ mouse, keyboard, scanner, network card, etc. ◮ Output devices ◮ screen/console, printer, network card, etc. ◮ Operating System ◮ Examples: Mac OS, Windows 10, Linux ◮ Controls computer operations ◮ Manages allocation of resources for currently running applications
Memory Concepts ◮ bit: a binary digit ◮ Stores the value 0 or 1 ◮ Smallest unit of storage in a computer ◮ byte: 8 bits ◮ Smallest addressable unit of storage in a computer ◮ Storage units (variables) in a program are 1 or more bytes ◮ Each byte in memory has an address (a number that identifies the location)
Programming, and Programming Languages Program - a set of instructions for a computer to execute Evolution of Programming languages ◮ Machine Language ◮ Based on machine’s core instruction set ◮ Needed by computer, hard for humans to read (1’s and 0’s) ◮ Example: 1110110101010110001101010
Programming, and Programming Languages ◮ Assembly Language ◮ translation of machine instructions to symbols, slightly easier for humans to read ◮ Example: ADD $R1, $R2, $R3
Programming, and Programming Languages ◮ High-level procedural languages ◮ Abstraction of concepts into more human-readable terms ◮ Closer to ”natural language” (i.e. what we speak) ◮ Easy to write and design, but must be translated for computer ◮ Examples include C, Pascal, Fortran ◮ Object-oriented languages ◮ Abstraction taken farther than procedural languages ◮ Objects model real-world objects, not only storing data (attributes), but having inherent behaviors (operations, functions) ◮ Easier to design and write good, portable, maintainable code ◮ Examples include Smalltalk, C++, Java
Code Translation Bridging the gap between high-level code and machine code ◮ Interpreted languages – source code is directly run on an interpreter, a program that runs the code statements ◮ Compiled Languages ◮ A compiler program translates source code (what the programmer writes) to machine language (object code) ◮ A linker program puts various object code files together into an executable program (or other target type, like a DLL) ◮ C and C++ are compiled languages
Software Development Involves more than just writing code
Software Development ◮ Analysis and problem definition ◮ Design - includes design of program or system structure, algorithms, user-interfaces, and more ◮ Implementation (coding) ◮ Testing - can be done during design, during implementation, and after implementation ◮ Maintenance - usually the major cost of a software system. Not part of ”development”, but definitely part of the software life cycle
Programming is about Problem Solving
